[tex]a(10x + 6) = 40x + b[/tex]
[tex]10ax + 6a = 40x + b[/tex]
Thus :
[tex]10ax = 40x[/tex]
x s simplifies
[tex]10a = 40[/tex]
Divide sides by 10
[tex] \frac{10a}{10} = \frac{40}{10} \\ [/tex]
[tex]a = 4[/tex]
_________________________________
And also must :
[tex]6a = b[/tex]
[tex]b = 6a[/tex]
[tex]b = 6(4)[/tex]
[tex]b = 24[/tex]
_________________________________
So :
[tex]a = 4[/tex]
[tex]b = 24[/tex]
Done...
